Tiny Snails with Door-Like Shells Discovered in Montenegro

September 24, 2026

Scientists have found two new snail species in Montenegro, each with shells that close like doors.

These discoveries highlight the biodiversity still hidden across Europe. One of these snails lives in the Komarnica Canyon, a threatened habitat due to plans for a hydropower reservoir. The construction could wipe out this unique ecosystem before its full scope is known, leading to irreversible loss of species.

The Komarnica Canyon's future hangs by a thread as developers push forward with plans that could destroy the snail’s home and other unknown wildlife.

If the proposed dam goes ahead, it will likely lead to long-term ecological degradation in the canyon, potentially erasing these newly discovered species from existence.

What is the long-term climate outlook for this region?

The discovery of these snails underscores the urgent need for environmental protection. The Komarnica Canyon faces threats beyond just hydropower, including broader climate impacts that could further degrade its habitat. Conservation efforts must prioritize understanding and safeguarding such unique ecosystems.

Conservation is critical to preserve this biodiversity.
